It is crazy how well the Super Zen and RF-7's fill a large open space. I have to say however there were times when I wished I had a few more watts, that is until I purchased the HSU Mid Bass Modules. These added a crazy Mid Bass Punch that two watts simply could not deliver.

The Super Zen just seems to do everything right with the mids and highs. The Mid Bass Modules reinforce the low end making the sound stage much bigger and meatier than you would think. Since the MBM purchase I have not wanted for more power.

For me the combination of the Super Zen, RF-7's and Mid Bass Modules is simply hard to beat.

There are two outputs on the CSP2+ One went to the Taboo MK III as a Pre-Out for the DM945's. The other I used the Right channel output to feed the Super Cube III Subwoofer. Pretty straight forward. Worked very well too.

May I ask how all those speakers are wired? Are they daisy-chained, or do you have Y adapters in front of the first two speakers on each channel?

Is anything connected to the "output to speakers" connectors on the MBM-12s?

The Left & Right are wired in a speaker level Daisy Chain configuration. From the Amp to Left & Right mains using Kimber 4TC speaker cable. From Left & Right mains to Left & right subs using CAT-5 cable. From Left & Right subs to Left & Right mid bass modules using CAT-5 cable.

The Mid Bass Modules have Speaker Level input connections (no Speaker Level output connections like you might find on some subs if that is what you are getting at). My mains are strong down to 50hz. The MBM simply augments the 50 to 150hz range. The MBM provides added density and a better 3D sense to the music.

For the record it seems my above statement was not entirely correct. The Mid Bass Module does have Speaker Level Inputs AND Outputs. Best I can determine there is no Crossover in the Output circuit (simply a pass-through) ???

On another note, The HSU "Quick Set-Up Guide" for the Mid Bass Module states: "Speaker Level connections are to be used only as a last resort. Much prefer line level connections".

I'm not sure why HSU suggests Speaker Level connections are inferior to Line Level connections? I'm having great results with Speaker Level connections.

I hadn't heard of using CAT-5 cables for speaker cables before. How do they connect? All eight wires in the CAT-5 wrapped around binding posts?

Is there a voltage regulator in these pictures, or am I thinking of somebody else?

I'm currently running my Subs and Mid Bass Modules in a Stacked Configuration. I'm using Aurlex Isolation Platforms between the Subs & floor and between the Mid Bass Modules and Subs.

Crummy photo but you can see Cat-5 attached to the Left Sub and daisy chained out to the Left Mid Bass Module. The Cat-5 consists of 4 twisted pair. I'm using 2 twisted pair for the + and 2 twisted pair for the -. It's important to note the Sub and Mid Bass Module place virtually no load on the amplifier so a very small wire gauge is fine for this purpose.

DBC, I'm sure those are sounding mighty fine. Those are ported in the back...right? Take a look at my post on the Deep Hemp Sub I bought this morning and tell me if I understand the hook up. I guess I need to order one of those Sub Dudes. Mark.
